Shirou's Return from the Fae Kingdom

How come the Arthur version of Shirou, who has lived for who knows how many years, speaks and acts like a middle school student, without any of the mannerisms you've created? Then, all the female characters are just skins and don't have a single bit of the original characters' personality traits. In the original story, Irisviel, who was willing to sacrifice herself for her husband and family in order to fulfill her husband's wishes and for her daughter's future, only saw two sides of the protagonist and was treated like a perverted woman who only knew how to have sex with underage girls. The writing style is also full of flaws. It has a kind of beauty to it, like when I was writing essays in high school, repeating the same sentence four times in different ways to pad the word count.

Regarding the Sea Demon arc, regardless of whether Shirou is a pure-blooded individual, he was thrown into the cesspool of the Fairy Kingdom at a young age and then fought for thousands of years. His seemingly innocent personality outside of combat is more like a self-defensive disguise due to maladjustment to modern society. It's highly possible that Shirou went mad from killing in the Fairy Kingdom; that could be considered his true nature, or perhaps a reaction to his battle form. Furthermore, even if the fairy version of Morgan is a kind savior, he ruled the chaotic Fairy Kingdom for so long; how could he not accept his partner of thousands of years being slightly mad? In the original work, regardless of the version, a large part of Shirou's underlying character is a result of Chizuru's upbringing.

The protagonist is a Type-Moon native in disguise as a transmigrator.

The author really doesn't plan to change the plot involving the sea monster? The protagonist suddenly starts acting crazy out of nowhere. I don't expect him to be mentally mature, but at least act like a normal person! And this is supposed to be the Nameless King, the Fairy Arthur? I ask you, where's the king? Where's Arthur? Is he some kind of chuunibyou king? His mentality isn't like an adult's; it's more like a primary school student having a fit, thinking that turning evil is cool and awesome.

When will author Shirou be able to win over Kallen?

The poison at the beginning was horribly bad, but it seemed okay after jumping to the end. The initial character development is completely unconvincing; it feels like a middle school student writing a novel. It's like they tried to reach a high level, but the result is shockingly flawed. If they're going to write like this, they might as well have just gone with the male protagonist from the previous book. Things returned to normal later on, and the protagonist's character design leaned slightly more towards the original Shirou. I feel this character design was handled better than in the previous book.

The protagonist is pretentious, and the women in his harem are mostly the ones who take the initiative. He's all talk and no action, but secretly he's a pervert. He says he doesn't want any ties to the past, yet he constantly brings it up. Couldn't the protagonist be a more proactive, carnivorous type, like saying, "My lady, you don't want to either?"

I've noticed something: Archduke's height of 163cm is exactly half the combined height of Lancer Artoria (171cm) and Saber Artoria (154cm). Even her height reflects that Archduke is a combination of all the ahoge (antenna-like hair strands) from the side. #(You know what I mean)

I have a small question. I think I saw someone say that the gods in the Age of Gods are all connected to the Root, and that Ayaka Sajō is just a modern goddess and not particularly special among the gods in the Age of Gods. Is that true?

Actually, setting aside mystery and technology, Shirou's martial arts skills are becoming increasingly valuable. It seems Shirou's mysterious aspects are nearing their peak, so we can explore that area further. Known examples of exaggerated martial arts displays or settings include: Heracles (whose martial arts are so powerful that even the Crown Spear needs to be equipped with them), Musashi and Kojiro (the Sky Sword and the equally powerful Infinite Sword; the former even managed to cut Kaguya in two in a scrapped design), Martha (whose physical prowess allows her to fight and suppress angels, and subdue a dragon with a few punches), and Li Shuwen (whose ability to put a beast to sleep with a single punch is so impressive that Qin Shi Huang spent centuries analyzing it).
